Not to alarm anyone but Natasha and I have a situation up top. A woman claiming to be Agent 19 of SHIELD has recently showed up. All well and good... except Agent 19 died awhile ago. We're not sure of who she is or her intentions. At this point it's possible she could be anything from a Hydra agent to another one of Loki's tricks.
Depending on the situation... or how accurate the illusion is... we may need some sort of backup.
